ABSTRACT
Periodic performance evaluations of employees are required in order to measure the contribution level of employee toward organizational objectives and also to calibrate individual performance. Performance evaluations of employees in organizations are customarily conducted via a formal performance appraisal system (PAS) (Gruenfeld and Weissenberg 1966, Rosen and Abraham 1966). In general, the PAS is administered on an annual basis to evaluate the performance of employee over a period of past 1 year (Bassett and Meyer 1968). Such annual PAS has been subject to criticism from the industry citing long frequency, among other drawbacks (Henderson 1980, Ilgen et al. 1981). Some industries such as Information Technology (IT) have tried to shorten this frequency by making it a half-yearly PAS.
